Description
Controls the automatic filling of a Params collection.
Use the ParamCreate property to control the automatic filling of a Params collection. If it is True, the SQL preprocessor scans the SQL command text for ':' symbols, it extracts parameter names and includes them into a Params collection. The scanning will be performed at each command text change. The default value is True.
Setting ParamCreate to False may be useful in the following conditions:
- The target DBMS uses ':' symbols in its own SQL dialect and FireDAC cannot recognize them as an SQL construction. Also, the SQL commands with these symbols may confuse the FireDAC SQL preprocessor.
- The SQL command cannot contain any parameters, like in a DDL SQL.
- The application does not use any parameters.
Setting PreprocessCmdText to False assigns a False value to ParamCreate.
